PaaS (Platform as a Service)

PaaS (Platform as a Service) provides a managed environment for developing, deploying and running applications without directly operating all underlying infrastructure. It may include runtimes, databases, queues, identity, scaling and tools, depending on provider and plan. The provider manages part of the platform while the customer retains responsibility for code, data, access, configuration, dependencies and cost. PaaS can accelerate deployment but may introduce limits, proprietary services and regional or vendor dependency. Before adoption, teams should review portability, network, observability, backup, recovery, updates, quotas and exit. High availability should not be assumed because a service is cloud-based; architecture and configuration matter. Load, failure and restore tests validate the design better than a feature list.
